Minerals were analysed using a Phenom XL scanning electron microscope (SEM) and, on polished thin sections, using a CAMECA SX50 electron probe micro-analyser (EMPA). Silicate minerals were analysed with a 15 kV and ~ 20 nA beam with 2–15 μm focal-spot diameter, while carbonates were...
With decreasing temperature and \\(a_{K^ + } /a_{H^ + } \\) of hydrothermal fluids initially in equilibrium with K-feldspar, the following alteration patterns developed within the porphyry, from the center outwards: silicification, K-silicate, phyllic and argillic alteration. The para...
The silicate-carbonate rocks with unique charoite rocks and "benstonite" Ba-Sr carbonatites crystallized from residual melts and fluids. The rocks of the massif have chemical, petrographic, and mineralogical affinities with lamproites. Isotope data indicate a deep mantle magma source for the rocks ...
